Not at all! You will be able to use your BRCK and use the cloud. What end-of-life means is we will no longer be making updates to the software and hardware on the actual BRCK. We have pushed out updates over-the-air in the last few months which will keep the BRCK running well.
We did to focus on building a better and more holistic device that can be and do more things than the BRCK V1.
If you have any other questions, I'm happy to answer them.
